The most traditional and popular among Russians is Sanduny. It has 2 separate bathing houses, one for men and one for women. The men's bathing house is like a Greek temple, with a large pool and nicely decorated entrance and dining hall. Unfortunately this is only open for women once a year. The women's part is more sober but still quite an experience.
This banya is smaller than Sanduny but is much more modern, with a nice & bright atmosphere. They have good and very clean facilities like, several steam rooms, a small cold pool and a proper dressing room. You can also book spa treatments and the prices are reasonable.
